Billie Eilish and Nat Wolff are spending more time together. The 23-year-old Grammy winner and the 30-year-old actor/singer enjoyed a romantic boat ride in Venice, Italy on Saturday, June 7, amid romance rumors between the two musicians.

In photos taken the same day, Wolff was seen kissing the "Happier Than Ever" artist and taking snaps of her as they sipped from champagne flutes. Rumors of a romance between the pair grew after they were seen leaving the iHeart Music Video Awards together and subsequently spending a night out in New York City, per Page Six.

Wolff (and his brother Alex) toured with Eilish last year and starred in her music video for "Chihiro," released in June 2024. At the time, they described their dynamic in the video as an "inescapable connection." Before that, they spoke about considering themselves good friends.

In an October interview with Variety, Nat spoke about how he and Alex bonded over having Tourette syndrome, "a disorder that involves repetitive movements or unwanted sounds (tics) that can't be easily controlled," per the Mayo Clinic.

"Even when I saw Billie on interviews, I said, 'Oh, she's one of us,'" said the actor/singer. "We know all the ways that we try to mute ourselves or try and chill ourselves out or soften ourselves for other people, and how nice it is to not have to do that for certain people."

Eilish spoke about their bond in a Vogue video. "My first real impression of you, when I met you, was at the Oscars after party, and I was sitting on the couch outside, and you just appeared," she joked. "It was just like an immediate — I don't even know what we talked about, but it was an immediate — I was like, 'Yo!'"

The "Happier Than Ever" artist has previously spoken about wanting to keep her love life private. "I wish no one knew anything about my sexuality or anything about my dating life. Ever, ever, ever," she told Vogue last year.

"And I hope that they never will again. And I'm never talking about my sexuality ever again. And I'm never talking about who I'm dating ever again," continued Eilish.
